Should I be worried? Parent's guide to typical and atypical teen behaviors

# How do I know if I should be worried about my teen's behavior?

As part of the process of maturing and gaining independence, teens do things that often make parents scratch their heads and wonder about these kids. It's no wonder that one of the many challenges of parenting is knowing when our child's behaviors are typical, atypical, dangerous, acceptable, or concerning. Have you asked yourself questions like...

  • Should I be worried that my teen only seems interested in staring at their phone hour after hour watching videos that seem inane and mind-numbing?
  • My teen drank beer over the weekend and then lied to me about it. How worried should I be?
  • Should I be concerned that my teen is sleeping a lot and seems uninterested in things they used to enjoy?
  • Do other teens fight with their parents as much as ours does with us?

We could go on, but suspect you get the point. Sometimes as parents we just want to know, is this behavior something I need to worry about or is it typical teen behavior?

To help shed some light on typical vs atypical teen behaviors, we enlisted one of our amazing company Science Advisors, Dr. Jacqueline Nesi (opens new window). Dr. Nesi is an Assistant Professor in the Department of Psychiatry and Human Behavior at the Warren Alpert Medical School of Brown University and a Clinical Psychologist at Rhode Island Hospital.

Below, Dr. Nesi provides some insights into several of the most common teen behaviors and suggests whether they are typical (you don't need to worry) or atypical (you should consider speaking with a professional).

A quick caveat - consider the information below suggestions and/or starting points. As the parent, it's always a good idea to keep an eye on any behavior you feel is or may become problematic.
